To aZZ whom it may concern:

Be it known that I, ALEXANDER GLAVEL, a citizen of the Swiss Republic,and resident of Basel, Switzerland, have invented a new and usefulApparatus for Smoothing Hanks of Textile Materials, of which thefollowing is a full, clear, and exact specification.

In the United States Letters Patent No. 972060 dated October 4, 1910, isdescribed an apparatus for smoothing hanks of textile materials,especially hanks of dyed silk, comprising a suspending roller upon whichthe hanks are to be suspended, a device for imparting to the suspendingroller a stepwise rotation on its own axis, a vertically movablestretching roller arranged beneath the said suspending roller, a liftingrod at-- tached to the said stretching roller, and a rotating engagingfork and two guides placed one on each side of the lifting rod, the saidengaging fork being so placed with regard to the lifting rod and to thesaid guides, that the fork in the course of its rotation passes betweenthe said guides and that during this passage its limbs are pressedagainst the lifting rod frictionally by means of the said guides,whereby the lifting rod together with the stretching roller is lifted,and, after the passage of the fork limbs between the guides, is allowedto fall down again.

The object of the present invention is to substitute in the saidapparatus for the engaging fork with elastic limbs and the two guidesplaced one on each side of the lifting fork a lifting device renderingthe operation more secure and the strength of stroke of the stretchingroller considerably more regular than it is possible with the devicedescribed in Letters Patent No. 972060. This improved device consists ofa rigid, vertically movableengaging fork and a clamping wedge serving tofix the lifting rod temporarily into the said fork under the action of apressure lever and of a rotary cam, in such a manner, that in the courseof the rotation of the said cam, the lifting rod is raised by the latterwith the fork and allowed to fall down again.

The drawing illustrates by way of example one form of carrying out theinvention.

Figure 1 is a vertical section. Fig. 2 is an end view and Fig. 3 is ahorizontal section of the improved lifting device of the apparatus. Fig.4: shows the apparatus in its entirety.

As in Letters Patent No. 972060 there is mounted in the machine frame 1,an upper suspending roller 2 (Fig. l) upon which the yarn hanks aresuspended, while beneath this suspending roller there is mounted thestretching roller 3 which is movable in the vertical direction andconstitutes a beating device. Both rollers are loosely and rotatablymounted upon their axes. The suspending roller 2 is provided with aratchet wheel 22 (Figs. 1 and 2) which on every stroke of the stretchingor beating roller 3 is moved forward to a predetermined extent, in aknown manner, through the medium of a pawl 20 in order to feed the yarnhanks intermittently forward. The pawl 20 is attached to a bent lever 21fixed on a rocking shaft 22 bearing an arm 23 provided with a roller 24:held in contact with a rotating cam 25 by a spring 26 pressing against afinger 27 of the said shaft 22. The actuation of the stretching orbeating roller 3 is effected in this case in a manner differing fromthat in Letters Patent No. 972060. The stretching or beating roller 3 ismounted upon a vertically movable lifting rod 4 which at the upper endpasses through a rigid fork 9 (Figs. 1 to 3); the latter is freelymovable in the vertical direction and its lowermost position isdetermined by a stop 10 (Fig. 1). Between the limbs or prongs of thefork 9 there is arranged a clamping wedge 11 and a pressure lever 12 ispivoted thereto. The latter is under the action of a rotating cam 13.

Assuming the parts are in the position shown in Fig. 1, when the cam 13rotates in the direction of the arrow, Fig. 1, the lever 12 is first soturned that its inner end or tail presses the wedge 11 tightly againstthe lifting rod 4 and thereby rigidly holds the latter in the fork byits clamping action, so that the further rotation of the cam 13 by itscontinued action upon the lever 12 raises the latter together with thefork and the lifting rod 4 until the said cam 13 releases the lever 12and wedge 11, whereupon the rod 4 drops with the stretching or beatingroller 3. As is obvious from Fig. 1, the stop 10 is adjustable in thevertical direction by means of the bolts 15. This enables the extent ofdrop of the fork 9 to be accurately regulated, since, the stop 10determines the lowermost position of the fork Which is freely movable inthe vertical direction.

What I claim is:

1. In an apparatus for smoothing hanks of textile materials, especiallyhanks of dyed silk, a suspending roller upon which the hanks are to besuspended, a device for imparting to the suspending roller a stepwiserotation on its own axis, a vertically movable stretching rollerarranged beneath the said suspending roller, a lifting rod attached tothe said stretching roller, a rigid, vertically movable engaging forkand a clamping Wedge allowing to fix frictio-nally the lifting rodtemporarily into the said fork and subjected to the action of a pressurelever and of a rotary cam in such a manner that in the course of therotation of the said cam the lifting rod is alternatively fixedfrictionally into the said fork by means of the said clamping Wedge,pressure lever and cam, in order to raise the lifting rod and thestretching roller together with the fork, and allowed to fall downagain.

2. In an apparatus for smoothing hanks of textile materials especiallyhanks of dyed silk, a suspending roller upon which the hanks are to besuspended, a device for imparting to the suspending-rollera stepwiserotation on'its oWn axis, a vertically movable stretching'rollerarranged-beneath the said suspending roller, a lifting rod attached tothe said stretching roller, a rigid, vertically movable engaging fork,having its lowermost position determined by an adjustable stop, and aclamping Wedge allowing to fix frictionally the lifting rod temporarilyinto the saidfork and subjected to the action of a pressure lever and ofa rotary cam in such a "manner, thatzin the course of the rotation ofthe said cam, the lifting rod is alternatively fixed frictionally intothe said fork by means of the said clamping Wedge, pressure lever andcam, in order to raise the lifting rod and the stretching rollertogether With the fork; and allowed to fall down again. y

In Witness whereof I have hereunto signed my name this 27th day ofMarch, 1912, in the presence of two subscribingwitnessesr V ALEXANDERCLAVEL. Witnesses:
